How to deal with the tar-like substance that forms in sulfuric acid storage tanks
Thread Content
What should be done regarding the tar-like substance that has formed in our facility’s sulfuric acid storage tanks, which contain sulfuric acid at a concentration of around 75%, as well as the partial crystallization? Steam tracing has been in use continuously, with the temperature ranging from around 70 to 110 degrees. Seek a solution.
The caking of sulfuric acid is mainly related to temperature control; keeping the concentration of sulfuric acid above 80% helps, and it’s also advisable not to use steam for heating, as this should lead to much better results.
Sulfuric acid is mainly used to remove sulfur and phosphorus from acetylene; upon looking inside the storage tank, a gel-like substance can be seen. Do any of you sea friends have any good ways to deal with this?
If steam tracing is not used, then what tracing method should be employed? The storage tank is located outdoors, where winter temperatures are around minus 20 degrees or lower.
Electric heat tracing provides uniform temperature with low heat generation, and it does not tend to form lumps
Thank you! So what are the ways to deal with the lumps in the storage tank now?
